This patchset introduces support for crypt-style passwords to unlock the console in autoboot mode.
The implementation of crypt-sha256 and crypt-sha512 originate from libxcrypt at https://github.com/besser82/libxcrypt.git Version v4.4.17 Git commit hash 6b110bc
I didn't re-format those two files to make diffing to the original versions from libxcrypt easier, which leads to a huge load of checkpatch.pl warnings&errors. Please advise on whether they should be re-formatted or can be kept as is.
The remaining warnings from checkpatch.pl are intentional resp. open for discussion.
A sandbox defconfig with password entry has been added. I'm not sure whether this should be kept or not, it's just there as an example.
Cheers, Steffen
